Happened suddenly. Parked, came back out. No reverse, shifter felt looser than normal. Tried to drive, stalled. Eventually realized I am stuck in third gear. I can move the shifter and feels like it is engaging in different gears, but only 3rd. Pull up on the collar for reverse, feels like reverse, but again only 3rd. I dont think it is the gear shift rod, since I can only be in 3rd. Any other pins that may have sheared?? All help appreciated. PS. Only 90,000 miles, original owner. No problems leading up to this.

Further troubleshooting: Noticed that it is not just 3rd gear. It appears moving the gear shifter for & aft, I am caught in 3rd and forth. When I try to engage side to side for 1st/2nd etc, movement but no engagement. I believe I only have the ability to move the gear selector rod in and out, but it wont turn.
